Heading C3P. A fluorohydrocarbon elastomer is dehydrofluorinated by dissolving it in an alkyl substituted amide solvent where the elastomer reacts with the solvent and undergoes a process of dehydrofluorination and then removing the solvent. Preferred amides are dimethyl-formamide and dimethylacetamide. The solvent may be refluxed. A salt may be dissolved in the solvent, the salt being an alkali metal or ammonium cyanide or thiocyanate or an alkaline earth metal nitrate, e.g. sodium cyanide or sodium thiocyanate. The preferred elastomer is a copolymer of hexafluoropropylene and vinylidene fluoride. The dehydrofluorinated polymer may be cured by heating with a curing agent, e.g. hexamethylene diamine, divinyl benzene or triallyl cyanurate. The dehydrofluorinated elastomer may be compounded with a polymer e.g. a fluorosilicone, and the compounded product cured.

A stabilized platform 16 for an inertial navigation system of an aircraft is supported in a three ring gimbal system comprising an inner roll gimbal 18, a pitch gimbal 20, and an outer roll gimbal 22 pivoted about the aircraft roll axis DD, the gimbals 18, 20 normally being maintained perpendicular to each other by a slave motor 66 acting on the outer roll gimbal 22 and controlled by a first synchro 62 between the gimbals 18, 20. To prevent gimbal lock during a vertical climb or dive, when the sensed pitch angle exceeds a predetermined numerical value, control of the motor 66 is switched to a second synchro 78 between the outer roll gimbal and the support frame. This causes the outer roll gimbal 22 to turn through 90 degrees to the position shown in Fig. 3 for the duration of vertical movement, and avoids the need for gimbal flipover. The platform 16 carries accelerometers 68, 70, 72 for inertial navigation, and also pitch, roll, and azimuth gyros 24, 26, 28 having pick-offs 34, 36, 44 and torque motors 38, 40, 46 respectively.
